The programs that produce the datasets needed for the analysis (and the cell level analysis datasets)
are in the directory "~/Data Files and Code That Produced Them". We used SAS 9.3 for Windows for the
data management and processing of the files. The code to create the figures, tables and appendices are
called in order in the Stata program "Reproduce Paper.do" with the exception of Tables 1 and 4 which 
are produced by SAS programs.
